200 Rounds of 55gr FMJ M193 5.56x45 Ammo by Winchester

Don’t let its fancy-sounding M193 designation fool you! This ammo is exactly what any AR-15 chambered for 5.56x45 likes to fire, and when it comes 200 rounds to a box you’re allowed to get creative. From lightning-fast mag dumps to careful long-distance shooting, Winchester USA does it all!

An M193 cartridge has a 55 grain FMJ projectile, and when loaded to a nearly Mach 3 muzzle velocity of 3,270 fps it follows a flat, accurate trajectory – not to mention inflicts big energy on impact. The bullet’s jacket is nonmagnetic and wears a cannelure around its middle to prevent setback while the cartridge is loaded in a magazine.

This ammo has new production and perfectly reloadable brass cases. USA brass looks a little discolored, but that’s simply the byproduct of the annealing process which left it more supple. Brass like that efficiently expands to seal the chamber, which promotes cleaner performance. Winchester’s low-fouling powder and non-corrosive primers promote cleaner performance still!
